Torchbeam D3S HID Bulbs 6000K Cool White 35W - Pack of 2, Quartz Glass & IP67 Durable

Torchbeam D3S 6000K 35W HID bulbs are plug-and-play xenon replacement lamps that deliver crisp, diamond-white light for compatible HID headlamp assemblies.

These Torchbeam D3S bulbs are designed as direct replacements for factory D3S/D3R xenon units (OEM numbers like 42403, 66340 and related references). They operate at 35 watts and emit a cool 6000K white beam that improves contrast on road signs and lane markings compared with warmer HID tones. Built with quartz glass, a shock-resistant aluminum base and an IP67 rating, they are intended for vehicles equipped with true HID/Xenon assemblies — not for halogen housings.

How bright and what color temperature will I see on the road?

The Torchbeam D3S bulbs produce a 6000K cool white light that appears crisp and slightly bluish-white. This color emphasizes roadside signs and reflective surfaces, offering clearer visual feedback than lower-color-temperature HID bulbs. Expect quick initial brightness rise typical of HID systems, reaching stable output after a few seconds.

• Color temperature: 6000K cool white for high contrast
• Power: 35W per bulb for factory-level output
• Warm-up: reaches optimal brightness within seconds

Will these fit my car and replace my current bulbs easily?

These units are specifically replacement D3S/D3R xenon bulbs and match common OEM part numbers such as 42403 and 66340. They are not compatible with halogen headlamp assemblies even if some fit listings appear similar. Confirm your vehicle uses an HID/Xenon ballast and socket type D3S before ordering.

• Fitment: D3S/D3R type only — check owner manual or existing bulb
• OEM cross-references: 42302C1, 42403(C1), 66340 and equivalents
• Installation: plug-and-play for compatible HID systems, no retrofit to halogen systems

How durable are these bulbs and how long do they last?

Torchbeam builds these bulbs with 100% quartz anti-UV glass and a shock-proof aluminum shell base to withstand heat, vibration and moisture. The IP67 waterproof rating reduces risk from rain or engine-bay contaminants, while the 35W power rating helps prevent rapid dimming. The listing includes a 24-month warranty for manufacturing defects.

• Material: quartz glass resists UV deterioration
• Protection: aluminum base with shock resistance and IP67 sealing
• Warranty: 24 months for manufacturing faults

What should I check before buying these HID bulbs?

Verify your vehicle's headlamp assembly type and socket compatibility, and confirm your car uses a xenon ballast for D3S/D3R bulbs. Note that many vehicles have more than two lamp assemblies; double-check which bulbs your model requires. If uncertain, consult the owner's manual or inspect the existing bulb for the exact type marking.

• Confirm: vehicle uses HID/Xenon assembly (not halogen)
• Check: bulb markings or owner manual for D3S/D3R designation
• Note: some vehicles require adapters or additional harnesses

Who is this for: The Torchbeam D3S 6000K 35W pair is aimed at drivers who need OEM-style xenon replacements that offer a cool white beam, reliable sealing against moisture and vibration, and straightforward fitment for D3S/D3R-compatible headlamp systems. It is suitable for owners seeking improved contrast at night without aftermarket projector retrofits — provided their vehicle already uses HID/Xenon technology.
